* <p>
* SizeChanges trigger an Surface.abort; if rendering were done in the same
* pass, rendering work done prior to the Surface.abort would be wasted.
*
- * Repacking is seperate from resizing since a box's size depends on
- * both the box's parent's size (so the traversal must be preorder)
- * contentwidths of siblings both before and after the box, which in
- * turn depend on all descendents of the siblings. FIXME
+ * The two passes are repack and resize. Together they are known as
+ * reflow. Repacking assigns boxes to the appropriate grid
+ * coordinates within the parents and computes
+ * contentwidth/contentheight. Resize computes actual size and
+ * position.
*
* A note on coordinates: the Box class represents regions
* internally as x,y,w,h tuples, even though the DoubleBuffer class
